Tried using 80% fan speed and about 6 out of 20 fan died after 3 months.... is it because of the sapphire brand I am using?
I am running my Sapphire HD7950 at 85% fan speeds. Does that mean I should be worried, too?
Different manufacturers have different issues, and will invest different amounts into the quality of their fans. I know currently MSI has several issues with their fans. I've used the Gigabyte WF3 coolers, and never had an issue with the fans.
